PRODUCTION AND CHARACTERIZATION OF INDUSTRIAL-USE SUBSTITUTED CHROMITE NANOPARTICLES

摘要

The present invention relates to the manufacture and characterization of a novel oxide material having a spinel structure with the formula CoFe0.8Cr0.8Er0.1Gd0.2Sm0.104. Said material has specific magnetic properties that are optimized and stabilized. The invention also relates to the preparation of said material and to the use thereof in the field of magneto-electric coupling and in solid oxide fuel cells. Specifically, the present invention relates to producing said compound in the form of relatively low-temperature nanoparticles. The invention is particularly useful in multiferroics, ferroelectrics, and antiferromagnetics.
